Connection Timed Out

Furiz · December 19, 2020

What can cause this, my IPv6 is off, connection is not over wifi.

Flappie · December 19, 2020

Hi. Please attach the dcs.log showing you disconnected.

( C:\Users\your-name\Saved Games\DCS...\Logs\dcs.log )

Furiz · December 19, 2020

Ok found this one, dcs.log.old

Says old at the end, but that is the only one I could find, last modified today, I guess its the correct one.

Your log doesn't show much connection-wise:

It seems your were in the multiplayer panel for 13 seconds and then you exit the game. It might not be the right log file.

What are your symptoms exactly? You were disconnected from a multiplayer game session, right?

Furiz · December 20, 2020

Yes, I get disconnected with the message "Connection Timed Out" and that server I was on is not shown on the server list, sometimes all of the servers are gone from the list, even tho those servers are online and running, I have to exit the game and reenter to fix that.

If it happens again Ill get the log asap, I think I entered the game again after that happened, maybe thats why there is nothing in the log.

Ok this is the log right after I got "Connection Timed Out" message today, see if you can find something.

Sorry, I don't see your PC disconnecting from the server. I see you entering an online server at 12.39 GMT but the log ends less than a minute after. Are you sure this is the right log?

When you get disconnected from a server, the log usually looks a bit like this:

2020-11-15 16:00:03.701 INFO    NET: disconnected from server
2020-11-15 16:00:03.701 INFO    Dispatcher: Stop

Was waiting for it to happen again, I think this time its the right one ;D

Thnx for your time to check this! and apologies if it is the wrong one again ;D

The "table is missing" messages are usual: nothing to worry about.

We can clearly see the disconnection was not planned, because of the absence of the usual "NET: disconnected: 0" message (exit code 0 means "exit as planned").

Unfortunately, there's not much information left. I'm curious: did the game say "Connexion Timed Out" this time?

Thanks

Yes I had the message "Connection Timed Out", I cant find any server when that happens and I have to restart DCS,

Today it happened again, maybe there is something different in this log,

dcs.log

I was wondering if it was something from my end, if I can do some router or network setup etc...

Edited February 17, 2021 by Furiz

Flappie · February 17, 2021

It's most probably something from your end that is causing this, yes. I'm assuming packets are sent both ways as they should (client app and server app) but your PC or network is filtering some of them, causing the end of the connection. That's the most probable cause to me.

Now, we need to figure it out. It could come from your antivirus, your firewall or your router. What are they?

You can start by adding these folders as exceptions in your antivirus:

D:\Games SSD\DCS World beta\
E:\CegaMega\DCS\

A good way to monitor network packets is to use Wireshark. You can install it (default installation), launch it, try to reproduce your issue, and if you succeed, attach the resulting TCP dump here.

Furiz · February 17, 2021

Alright, thnx for taking the time to check this out.

I suspect it is probably Avast anti-virus, firewall is set to on with everything, and Router is Technicolor TG788ivn v2

I'll try with Wireshark, but the "connection timed out" doesn't happen every time I play, so who knows how long it will take to disconnect me again like that;P

Flappie · February 17, 2021

I understand. In that case, forget about Wireshark, becaue TCP dumps quickly take a lot of space when playing! Only use Wireshark when you're sure you can reproduce the issue in a matter of minutes.

Simply add the DCS folders as exceptions in Avast, then pray for the disconnections to never happen again.

Can someone take a look in my log file, I had 2 connection timed outs in 2 hours. And internet seems to work just fine (did few tests in last 15min).

Didn`t have these issues until today, and I don`t have any additional anti virus (only default Win10s).

dcs.log

Do you get disconnected after a fixed period of time? Say every 60 minutes or so? If so, it could be a QoS issue with your router.

wormdoktor · March 30, 2023

Also having this issue, only for the last 3 or 4 days, have never experienced this previously. Repeatedly getting "connection timed out" message when logged into Hoggit servers. Sometimes happens within seconds of login, sometimes after 15-20 min. Haven't changed anything on my PC to correlate with this issue. Log file attached. Please help!

Edit: Same thing just happened on Flashpoint Levant:

Hi. Your log doesn't show the same error:

2023-03-30 21:24:19.867 INFO    ASYNCNET (Main): client has started
2023-03-30 21:24:19.867 INFO    ASYNCNET (Main): Using LEDBAT for UDP congestion control.

2023-03-30 21:24:28.132 ERROR   ASYNCNET (10660): HTTP request dcs:serverlist failed with error 6: Couldn't resolve host name

It seems DCS encountered a DNS issue: it couldn't resolve the hostname it was given.

Try to reboot your internet router and see if the issue keeps happening. If it does, check your DNS settings.

Thanks for quick response, I'll give that a go.

Rebooted router, reinstalled dcs, still seeing same error 6. Latest 2 logs attached. Any suggestions on what to do next? Not sure what "checking my DNS settings" means I'm afraid. Help much appreciated.

hello. this is just like a post i participated in back is 2020. can you get to these two sites?

https://cdn.digitalcombatsimulator.com/

https://updates.digitalcombatsimulator.com/

these host are on systems in VA, US. where are you located?

Flappie · April 4, 2023

A DNS translates hostnames (e.g. "www.digitalcombatsimulator.com") into IP adresses. Humans use hostnames ; devices use IP adresses.

See, if I ping DCS website, my PC answers me by providing the website IP address:

But my PC does not know the IP address of every device connected to the Internet. It has to use a DNS service. Most of the time, our devices uses the router DNS service, which seems logical. Yet sometimes, people prefer their PC to use a different DNS service. A part of them use Google DNS, for instance.

According to your DCS log, DCS is unable to retrieve the IP address of the DCS update server, which puts an end to the update process.

Please answer @silverdevil's questions, we'll get to the bottom of this.

is this issue completely reproduceable? meaning every time and every server?

Should I download and install those updates?

Every server so far, I'd say every time as long as I'm on for long enough. Time to crash is variable. I'll keep recording log files from now.
